2. The participant has documented chronic HCV GT3-infection (with no evidence of nontypeable or mixed GT) as follows:
a) positive for anti-HCV antibody, HCV RNA, or HCV GT3 at least 6 months before Day 1, or
b) positive for anti-HCV antibody or HCV RNA with a liver biopsy consistent with chronic HCV infection (such as the presence of fibrosis) before Day 1
3. The participant has liver disease staging assessment as follows:
a) Absence of cirrhosis (F0 to F3) defined as any one of the following:
i. a liver biopsy performed within 24 months of Day 1 showing absence of cirrhosis, or
ii. FibroScan® performed within 12 months of Day 1 with a result =12.5 kPa,or
iii. FibroSure® (FibroTest®) performed during Screening with a score of =0.48 and an aspartate aminotransferase to platelet ratio index (APRI) =1

7. The participant provides written informed consent for the study
8. The participant has HIV infection documented at any time prior to screening by any licensed rapid HIV test or HIV enzyme or chemiluminescence immunoassay (E/CIA) test kit and confirmed by a licensed Western blot or a second antibody test by a method other than the initial rapid HIV and/or E/CIA, or by HIV p24 antigen, or plasma HIV RNA VL

6. A WOCBP is expecting to conceive or donate eggs from Day 1 through at least 14 days after the last dose of study treatment or longer if dictated by local regulations
7. The participant has any of the following conditions:
a. organ transplants (including hematopoietic stem cell transplants) other than cornea and hair
b. poor venous access that precludes routine peripheral blood sampling required for this study
c. history of gastric surgery (eg, stapling, bypass) or malabsorption disorders (eg, celiac sprue disease)
d. any clinically significant cardiac abnormalities/dysfunction that may interfere with participant treatment, assessment, or compliance with the protocol, including but not limited to: unstable angina, unstable congestive heart failure, unstable arrhythmia; participants currently under evaluation for a potentially clinically significant cardiac abnormality/dysfunction are also excluded
e. any major medical condition, clinically significant illness (other than HCV), pre-study laboratory or ECG abnormality, or history of any illness, which, in the opinion of the investigator, might interfere with participant treatment, assessment, compliance with the protocol, or confound the results of the study or pose additional risk in administering the study drug to the participant
f. history of a medical/surgical condition that resulted in hospitalization within the 3 months prior to enrollment, other than for minor elective procedures
g. medical /surgical conditions that may result in a need for hospitalization during the study duration
h. any medical condition requiring, or likely to require, chronic systemic administration of corticosteroids, tumor necrosis factor antagonists, or other immunosuppressant drugs through FW24
i. life-threatening serious adverse event (SAE) during the screening period
j. evidence of history of chronic hepatitis not caused by HCV, including but not limited to, drug-induced hepatitis, hemochromatosis, Wilson’s disease, a1-antitrypsin deficiency, alcoholic liver disease, and autoimmune hepatitis
